The records show Hunter is due in court Jan. 5 for a change of plea hearing. Previously, he and his wife, Shauna, pleaded not guilty to the charges in a nine-count superseding indictment issued in September.

"Like Brother Letten, I can't comment one way or the other," Lemann said.

The indictment says Shauna Hunter told her insurer that her black BMW 525i was ruined by the floods after Hurricane Katrina. But prosecutors allege that the vehicle was undamaged and that the couple continued to drive it.

Nonetheless, Shauna Hunter received a $3,443 check from her insurer, AAA, which also paid off the car's $55,000 note, according to the indictment.

Authorities began investigating after the car was spotted twice running red lights in New Orleans. Because AAA by then technically owned the car, it also received notices of the traffic violations. The Hunters tried to hide the car in an airport parking garage, according to the bill of information, but it was discovered there by a New Orleans police detective.

The Hunters were charged with conspiracy, obstruction of justice, lying to the FBI, and transporting and concealing a stolen motor vehicle.

Sean Hunter resigned from his airport post in September 2009 after news of the federal investigation broke.

The Hunters were initially charged in August 2010 in a one-count bill of information. But they backed out of a plea agreement and were then hit with a nine-count indictment. The new court filings do not indicate how many counts Sean Hunter will plead guilty to, nor do they indicate whether Shauna Hunter also intends to plead guilty.

Shauna Hunter is charged in a separate two-count indictment in federal court in Houston. That case, which involves the same set of facts as the New Orleans case, is set for trial Jan. 24. The New Orleans case is set for trial Feb. 28.
